BBDC vs CDC vs SSDC — The Official Pass Rates, Straight From the Traffic Police
The Traffic Police publish first-attempt pass rates and waiting times for every Singapore driving centre. The gaps between them are much larger than most people expect.
Most articles comparing Singapore's three driving centres are guessing, or quoting a figure someone posted on a forum years ago. They do not need to be. The Traffic Police publish the actual numbers, refreshed regularly, on their own Knowledge Hub.
Below are the current published figures, covering June 2025 to May 2026, with waiting times as at May 2026.
First-attempt pass rates
| Test | BBDC | SSDC | CDC | Private instructor |
|---|---|---|---|---|
| Basic Theory Test | 94% | 86% | 86% | 67% |
| Final Theory Test | 97% | 91% | 86% | 75% |
| Class 3 Practical | 51% | 40% | 31% | 26% |
| Class 3A Practical | 53% | 52% | 39% | 31% |

Bukit Batok leads every category. Its BTT figure comes from a large sample — 11,165 passes out of 11,934 first attempts — so it is not a small-numbers artefact.
The number that should actually worry you
Look past the theory columns. Roughly half of all Class 3 practical candidates fail on their first attempt, everywhere. Even at the strongest centre it is 51%. At CDC it is 31%, and among private-instructor candidates it is 26%.
The theory tests, by contrast, sit between 86% and 97%. These are not comparable difficulties, and they should not get comparable preparation. The practical test is the one that will cost you money and months.
Why private candidates trail — and what it does not mean
Private-instructor candidates come last in all four rows. It is tempting to read that as "private instructors are worse." That is not what this data can tell you.
The centres and the private route attract different people. Centres bundle structured theory lessons and internal assessments; the private route is cheaper, more flexible, and more self-directed, which suits disciplined learners and punishes people who under-prepare. The figures measure outcomes, not instruction quality, and nothing here isolates the instructor's contribution from the student's.
What the gap does tell you is that the private route puts the burden of structure on you. If you take it, you have to supply the discipline the centre would otherwise have imposed.
Waiting times are the tie-breaker
Pass rates are only half the decision. Booking delays vary too, in months:
| Test | BBDC | SSDC | CDC |
|---|---|---|---|
| Basic Theory Test | 0.2 | 0.9 | 0.8 |
| Final Theory Test | 0.2 | 0.2 | 0.4 |
| Class 3 Practical | 0.7 | 0.6 | 0.5 |
| Class 3A Practical | 0.7 | 0.6 | 0.3 |
Note the reversal. Bukit Batok has the shortest theory waits and the longest practical waits — its popularity works against it exactly where the queue costs you most. If finishing quickly matters more to you than a few percentage points of pass rate, CDC's practical waits are less than half of BBDC's.
How to read all of this
Do not pick a centre on pass rate alone. The figures reflect who enrols as much as how well anyone teaches, and a 3-point difference is not something you personally will feel.
What is worth acting on:
- The practical test is the hard one. Budget time and lessons accordingly.
- Waiting times compound. A 0.9-month theory wait plus a 0.7-month practical wait is most of a semester spent queueing.
- Theory is the cheap win. Pass rates of 86–97% mean the bar is clearable by anyone who actually prepares. Failing theory is almost entirely avoidable, and it delays everything downstream.
Check the Traffic Police page yourself before deciding — it is updated as new figures come in, and the numbers above will eventually go stale.
